Answer:
Step-by-step explanation:
Find the area of the shape by creating two shapes. A large rectangle and a very small triangle. The area of the rectangle is 13x12, and the area of the triangle is (1/2)3x4. The area of both shapes together is 6+156=<u>162</u>.
Now you can easily calculate the area of each rug and determine whether it is over half of 162 (because 162 is the area of the entire floor), or under half of 162. If it is under 81, then it does not cover at least half of the floor.
12x6 = 72 no
10x9 =90 yes
13x12 = 156 yes
3x12 = 36 no
8x8 = 64 no
Hi,
f°g means : apply first g then f . so calculate "g" and then use result as "x" in f.
g°f means : you apply first f then g
so : f°g = 2(3x²-x) -5 = 6x²-2x- 5
To improve in math, you need practice. have a try with g°f :)
give the answer in comments, and I will tell you if you are correct.
good luck.

Answer:
- geometric
- arithmetic
- neither (Fibonacci sequence)
Step-by-step explanation:
If ratios are the same, it is geometric:
8/4 = 16/8 = ... = 2
If differences are the same, it is arithmetic:
-4-(-8) = 0 -(-4) = ... = 4
If neither is the case, it is neither:
3-2 ≠ 5 -3
3/2 ≠ 5/3
In this last sequence we see that differences equal the previous term. This is characteristic of the Fibonacci sequence, which sees wide use in Nature, and has a relationship to the Golden Ratio. (The ratios of successive terms approach the golden ratio (1+√5)/2 ≈ 1.618.)
